defaultsetup.conf: enable select init manager

Introduce a new variable INIT_MANAGER and create 4 init-manager-*.inc
files to configure init manager settings. Available values of
INIT_MANAGER are sysvinit, systemd, mdev-busybox and a default of none.
'none' provides backwards compatibility.

The settings of various VIRTUAL-RUNTIME variables are moved into these
files from the packagegroups.

[YOCTO #13031]

[Modifications by RP for backwards compatibility]
